Painted Reed Frog

Fascinating facts about the Painted Reed Frog

• The male's call lasts just 0.1 seconds, rings at 2.8-3.1 kHz, and a huge vocal sac makes it loud enough to be heard over rivals. Two males may call together, alternating with a third, but females avoid clusters, preferring a single male at least 50 cm away.
• When the dry season hits, painted reed frogs shrink their water loss to a whisper, losing far less through skin than most frogs. They adopt a water-conserving pose, rest motionless on a single leaf, and even turn white to reflect scorching sun. Their skin crystals, built from food-derived purines, act like tiny mirrors, cutting heat load. By storing water in a bladder and releasing it through the skin to evaporate, they can cool themselves without drinking.
• A single female painted reed frog can lay between 150 and 600 tiny eggs, each just 1.3-1.5 mm across and tucked inside a 2.5 mm capsule. She drops clumps of about 20 eggs onto underwater plants during the rainy season, and may repeat this every two to three weeks for over a year. With an average clutch of 300-400 eggs and a five-day hatching time.
• The painted reed frog's bright red skin on the inside of its thighs and belly acts like a hidden alarm clock. When the frog leaps, the flash startles predators such as frog-eating bats, green snakes, and kingfishers, buying the frog precious seconds to escape. This concealed warning color shows how even tiny amphibians evolve clever tricks to survive in predator-rich African savannas.
• Painted reed frogs grow fast: tadpoles hatch in under a week and become froglets in just two months, reaching up to 44 mm before metamorphosing. In captivity the whole transformation can take 64-100 days.
